and the second resetting mechanism 13 is arranged at the bottom end of the second rod body 5, and the second resetting mechanism 13 is connected with the second measuring body 8 and used for enabling the second measuring body 8 to move towards the direction close to the first measuring body 6.
In particular, a measuring space is formed between the first measuring body 6 and the second measuring body 8, when the thickness measuring device of the redwood furniture of the present invention needs to perform thickness measurement on a certain component of the redwood furniture, a human inspector manually separates the first measuring body 6 from the second measuring body 8, and the object to be measured 25 is placed in the measuring space, the first measuring object 6 moves towards the direction close to the second measuring object 8 along the first rod body 4 under the action of the first resetting mechanism 12, so that the first contact mechanism 10 is contacted with the upper surface of the object to be measured, the second measuring object 8 moves towards the direction close to the first measuring object 6 along the second rod body 5 under the action of the second resetting mechanism 13, so that the second contact mechanism 11 is in contact with the lower surface of the measured object, and the measured object 25 is clamped. The ultrasonic ranging sensor 9 on the second measuring body 8 emits ultrasonic waves and reflects the ultrasonic waves into echo waves after contacting the sensing piece 7, so that the distance between the first measuring body 6 and the second measuring body 8 is measured to be D1, and the length D2 of the first contact mechanism 10 and the length D3 of the second contact mechanism 11 are subtracted, so that the thickness D of the measured object 25 is obtained to be D1-D2-D3. The thickness of a certain part of the redwood furniture is measured by ultrasonic ranging, compared with the thickness measurement of a graduated scale in the prior art, the thickness measurement method has high measurement accuracy, the surface of the redwood furniture cannot be scratched, and the thickness of the redwood furniture can be measured when parts with partial irregularities are met.
Furthermore, one end of the handle 1, which is far away from the connecting hole 2, is provided with a grabbing part 14, and the grabbing part 14 is provided with anti-skid stripes. Specifically, in order to facilitate the detection personnel to grasp the invention, the handle is provided with a grasping part 14, and the grasping part 14 is provided with anti-slip stripes to prevent slipping.
